The sugar pop star brought the jungle to the stage when she performed her hit "Roar" on Saturday Night Live last night. Katy donned a teeny tiny leopard print dress, while her band wore animal costumes. From an elephant to a parrot, her musicians had the animal kingdom covered. That's as rock and roll as it gets! "Yes, the zoo animals have been a bit bored since the government shutdown so I invited some of them on stage with me tonight... #SNL," she tweeted.

Katy, who was host Bruce Willis' musical guest, later made a wardrobe change to perform her newest single "Walking on Air." Her band coordinated their outfits again, but this time, it was head to toe white. Katy herself sported a short black and white plaid skirt, white crop top and white knee-high socks. In other words, she was a school girl, through and through.
